Definitions

  • the lubricant pressure building up in the metering chamber displaces the amount of lubricant present in the metering chamber between the valve piston and metering piston in at least one lubricant outlet and the valve piston is moved until the pressure equalization point is reached by the metering piston into an intermediate position in which the valve piston allows the passage of the lubricant inlet to the connecting channel and thus to the dosing chamber shuts off.
  • the valve piston and then also the metering piston are returned to its starting position by the single return spring.
  • the solution according to the invention can be implemented in one embodiment in that, for example, between the first return spring and the second return spring, a e.g. essentially hollow cylindrical support body for the two return springs is arranged.
  • the passage possibly present in the support body permits the passage of an extension of the metering piston facing the valve piston, so that when the metering piston is confirmed by the pressure built up in the metering chamber, the valve body can initially be displaced from the metering piston in the direction of its starting position into an intermediate position in which the lubricant inlet is separated from the connection channel.
  • the support body can in turn rest against a contact shoulder of the valve housing facing away from the valve body.
  • FIG. 2 shows a representation according to FIG. 1 for another exemplary embodiment of a distributor element according to the invention.
  • the single-line distributor shown in the drawing for dosing lubricants, such as grease, for single-line lubrication systems has a distributor housing 14 with a through-channel 13 which extends over the length of the distributor housing 14.
  • a lower closure body 16 with a lubricant inlet 6 is screwed into the lower end of the valve housing 14.
  • the lubricant inlet 6 opens into an axial inlet channel 6 ′′, which leads to a valve piston 1 which is axially displaceably received in the through channel 13 and which is arranged on the side opposite the lubricant inlet 6 in the through channel 13 and is coaxially arranged in the through channel 13.
  • the connecting channel 5 leads at its upper, i.e. its end facing away from the valve piston 1 into a metering chamber 4, which is delimited within the through-channel 13 with respect to the valve piston 1 by a metering piston 9 provided with a peripheral seal 17.
  • the metering piston 9 is supported in the direction of the valve piston 1 via a second return spring 10 on the side of the support body 12 facing away from the valve piston 1.
  • the metering piston 9 can protrude with a control pin section 18 into an upper, laterally open closure body 19 for the optical function display.
  • the metering piston 9 can have an extension 20 for pushing back the
  • Valve piston 1 in the direction of its starting position before the end of
  • Lubricant outlet 11 which in the initial position shown in Fig. 1 of the
  • Valve body 1 may be directly in front of the end face of the metering piston.
  • a lubricant passage 11 'provided with a screw plug 21 can be used, for example, to fill the distributor element with lubricant.
  • the functioning of the invented distributor element is as follows:
  • the pressure present at the lubricant inlet 6 of the distributor element is relieved to a residual pressure.
  • the two return springs 7, 10 are relaxed to the respectively desired and appropriately designed pretensioning force.
  • the allocation chamber 3 - after the first filling via a lubricant passage 11 '- is filled with lubricant from the previous lubrication cycle.
  • the corner 2 bore still connects the dispensing chamber 3 to the metering chamber 4 via the connecting channel 5.
  • a central lubrication pump builds up the lubricant pressure in the main line and in the lubricant inlet 6, 6 'to a working pressure.
  • the valve piston 1 is advanced by the working pressure against the action of the first return spring 7 until it opens the passage 8 in the valve housing 14 to the metering chamber 4 via the connecting channel 5.
  • the lubricant supplied by the lubricant inlet 6 then passes through the connecting channel 5 into the metering chamber 4.
  • the metering piston 9 is acted upon by the lubricant pressure arising in the metering chamber 4 and is actuated against the action of the second return spring 10.
  • the control pin section 18 which may be present is drawn in at the same time.
  • the metering piston 9 has displaced the amount of lubricant to be metered from the metering chamber 3 to the lubricant outlet 11 (or 11 ') and, with its extension 20, which may be provided, has moved the valve piston 1 to an intermediate position in which the passage is reached when the pressure equalization point is reached 8 to the connecting channel 5 is blocked off by the rear section of the valve piston 1.
  • the distributor element remains in this position until a pressure relief valve of the lubricant pump is actuated.
  • the lubricant line between the lubricant pump and the lubricant inlet 6 of the distributor element is relieved of pressure after completion of each lubrication in a subsequent pressure relief phase.
  • a lower pressure drop to a desired residual pressure of, for example, 90 bar is sufficient compared to conventional distributors.
  • the first return spring 7 moves the valve piston 1 from the intermediate position initially assumed (downward) to the end position shown in FIG. 1 (which represents the initial position for the following lubrication cycle).
  • the metering chamber 4 is now connected to the dispensing chamber 3 via the connecting channel 5, the re-opened passage 8 and the bore 2.
  • the second return spring 10 can now transfer lubricant present in the metering chamber 4 into the dispensing chamber 3 via the connection path mentioned and fill it.
  • the distributor as a whole has returned to its starting position in this lubrication cycle and a new lubrication cycle can be started begin, the design of the second return spring 10 independent of the first return spring 7 ensures the desired low minimum working pressure.
  • FIGS. 2 and 2A The embodiment of a distributor element according to the invention shown in FIGS. 2 and 2A does not differ in its basic function from the distributor element shown in FIGS. 1 to IB 2 .
  • this distributor element is constructed somewhat differently in that the support body 12 is designed as an elongated sleeve body coaxial with the two return springs 7 and 10, in which the upper section of the first return spring 7 is accommodated.
  • the first return spring 7 is supported on an upper, in other words on the end of the support body 12 facing away from the valve body 1, radially inwardly facing flange 24.
  • the second return spring 10 engages around the sleeve-shaped section body 12 with its end facing the valve body 1 and is supported on a radially outwardly projecting foot flange 23 of the support body 12.
  • the two return springs 7, 10 can have relatively large lengths with a corresponding spring characteristic, despite the length of the distributor element remaining the same.

Abstract

Elément distributeur, en particulier distributeur d'introduction, pour le dosage de lubrifiants pour des systèmes de lubrification, qui comporte un piston (1) à soupape pourvu d'un trou (2). Ledit piston peut être déplacé d'une position de départ dans laquelle le trou (2) libère une liaison entre une chambre de répartition (3) et une chambre de dosage (4) via un canal de liaison (5), sous la pression du lubrifiant existant au niveau d'un orifice d'entrée (6) de lubrifiant et contre l'action d'un premier ressort de rappel (7), jusqu'à une position de dosage dans laquelle le piston (1) à soupape libère un passage (8) reliant l'orifice d'entrée (6) de lubrifiant au canal de liaison (5) et, partant, à la chambre de dosage (4). Ledit élément distributeur comporte en outre un piston de répartition (9) qui peut être déplacé sous l'effet de lubrifiant entrant dans la chambre de dosage (4), contre l'effet d'un second ressort de rappel (10), à partir d'une position de départ, et qui par là même contraint la quantité de lubrifiant présente dans la chambre de répartition (3) entre le piston (1) à soupape et le piston de répartition (9) dans un orifice de sortie (11) de lubrifiant. Le piston (1) à soupape peut être éventuellement déplacé, jusqu'à atteindre le point d'équilibre de pression, dans une position intermédiaire dans laquelle il bloque le passage (8) reliant l'orifice d'entrée (6) de lubrifiant au canal de liaison (5) et, partant, à la chambre de dosage (4). En cas de décompression au niveau de l'orifice d'entrée (6) de lubrifiant, le piston (1) à soupape est ramené par le premier ressort de rappel (7) dans sa position de départ et le piston de répartition (9) est ramené par le second ressort de rappel (10) dans sa position de départ.
